Blender Eevee HDRI reflection makes the color surface of objects wrong
Unlike Cycles, Eevee is not capable of global illumination. The objects in your scene are only lit by the hdri - which does not create shadows. This means that the ceiling is just going to reflect the grass, even though other objects are in the way.
Setting up realistic lighting in Eevee is a science in itself, but to fix the ceiling it should be enough to set up an irradiance volume to represent the bounced light in your room.
To do this, add an &quot;irradiance volume&quot; and scale it on the respective axis so it just encompasses the whole room. Then, under &quot;indirect lighting&quot; in the &quot;render&quot; tab hit &quot;bake indirect lighting&quot;. This will calculate the lighting conditions on each of the probes, which will then be used for reflections.

In the first picture you can see that the ceiling has the brown-ish look of my hdr. If i add an irradiance volume the room is properly lit, with the missing texture giving the light a pink hue.
But honestly, it takes quite some work to make lighting look realistic in eevee, especially if you want to use an hdri. I'd recommend using cycles for the final render and to check lighting, while limiting eevee for previews.
